TPM Series transmitters deliver a 4-20mA output that is proportional to the pressure directly detected by a four-arm, active strain-gauge bridge that is formed from highly stable resistors fused to a high purity ceramic pressure-sensing element. Internally, the electronic elements comprise a primary signal processing module that utilises an ASIC-based high‑speed digital signal processor and a separate board that handles the interface and EMC immunity and emissions requirements.
Featuring a stainless steel housing, the rugged construction of the TPM Series transmitters is complemented by a choice of pressure ports and electrical connections. The family supports options for gauge, sealed gauge, absolute and compound pressure types and offers 18 pressure ranges from 0-100 mbar to 0-600 bar. Further options allow for different pressure connection materials and seal types, which include EPDM for portable water applications.
